DANIEL WV. COLE, OF OTTAWA, KANSAS, ASSIGNOR TO WILLIAM W. DE WOLF, OFSAME PLACE.

HYDROCARBON-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 512,245, dated January2, 1894.

To all whom it may concern.-

Be it known that I, DANIEL W. COLE, a citizen of the United States,residing at Ottawa, in the county of Franklin and State of Kansas,haveinvented certain new and useful Improvements in Hydrocarbon-Burners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in hydrocarbon burners of thatclass which supplies a liquid hydrocarbon to a retort for the purpose ofvaporizing the liquid and feeding it in a heated condition to the flameorifices or nipples of the burner; and the object in view is to providea simple and inexpensive apparatus of this character for domestic andgeneral heating purposes. To the accomplishment of these ends, Iconstruct the burner with a retort having an internal spreading tubewhich is held in position within the retort in a manner to receive uponitself the liquid hydrocarbon supplied by a pipe from an elevated tank,whereby increased heating surface is provided within the retort, theliquid hydrocarbon is spread and diffused quickly over the heatingsurface, and the vapor can pass freely through the retort and itsinternal pipe. With this retort I combine a heating chamber which issituated above. the same and connected thereto by a pipe through whichthe vaporized fuel from the retort can pass to said heating chamber, andto this latter chamber I connect or couple in any suitable way the endsof a bow-shaped pipe which extends below the retort and is provided, inits horizontal lower part, with a series of flame orifices or nipples towhich the vaporized fuel, in a heated condition from the upper heatingchamber, is supplied for consumption.

The improvements further consist in the peculiar construction andcombination of parts which willbe hereinafter fully described andpointed out in the claims.

In the accompanying drawings, forming a part of this specification, Ihave illustrated the preferred embodiment of my improved hydrocarbonburner, in which- Figure l is a perspective view, and Fig. 2 is avertical longitudinal sectional view taken through the retort and theheating chamber, Like letters of reference denote correspond ing partsin both figures of the drawings, .re--

ferring to which A designates the retort which consists of the longcylindrical tube having the closed ends a, a, and the internalconcentric spreader tube B. This internal tube is of less diameter thanthe retort-tube A, and it is held therein in a fixed position,concentric with the retort-tube by means of the skeleton rings 0, O,which are constructed to permit the vapor or liquid to pass freelythrough the tubes A, B, and around the internal tube B.

D is the elevated tank in which the liquid hydrocarbon is placed and Eis the supply pipe which has one of its vertical branches connected tothe lower part of the elevated supply tank while the other vertical armof this supply pipe is connected to the top side of the retort-tube A ina position or manner for the liquid hydrocarbon to drop upon theinternal diffusing tube B within the retort.

F is the upper heating chamber which is vmade in the form of acylindrical tube situated above or immediately over the retort A, andthe ends of this tube F are closed in any suitable way. I may close theends of the tubes A, F, by means of screw-plugs that are designed to bescrewed into the ends of the tubes, or these plugs may be welded intothe ends of the tubes; butin lieu of plugs I may employ external caps asshown in the drawings which may be screwed or otherwise securelyfastened onto the ends of the tubes A, F, the object being to verytightly close the ends of said tubes to obviate the escape or leakage ofthe vaporized fuel in any manner.

G is the bow shaped pipe that forms the burner, proper. This pipe isbent from a single continuous piece or length of tubing to form thelower horizontal branch 72. and the upright branches i, 1', the pipebeing arranged as shown in Fig. 1 of the drawings. The ends of theupright branches '5, '6, of the pipe G are securely fastened to therespective caps or plugs at the ends of the heating-chamber tube F so asto receive the hot vaporized fuel from the chamber in said tube F whilethe lower horizontal branch h of this pipe G 1s arranged below theretort A-and in close pro cimity thereto. In the upper side of thishorizontal branch h of the bow shaped pipe I provide the flame orificesJ. These orifices may be in the form of round or oblong holes cut 1n theupper side of the branch h, ortapered nipples may be secured to theupper, side of the branch h of the bow-shaped pipe G.

In the vertical branch of the supply pipe E which is connected to theelevated tank is provlded a regulating cook or valve 6 by which the flowof'liquid hydrocarbon through the supply pipe E can be regulated so asto prevent flooding with the tank I provide suitable indicatingmechanism to indicate the quantity of liquid hydrocarbon that shouldbesupplied to the re- "tort to govern heating capacity of the burner. I

This being'the'construction of my improved hydrocarbon burner, theoperation may be briefly described as or tray is placed underneath theburner and a quantity of "liquidhydrocarbon is deposited 'th'erei'n,after which a lighted match or taper is applied to the liquid in the panor tray and the heat thereby produced serves to heat the retort, thebow-shaped pipe G and the heating chamber tube F. The valve 6 is nowopened to permit the liquid hydrocarbon to pass through the pipe E intothe retort and uponlt'he interna'ltube B'therein, which causes theliquid to'be quickly diffused over the heating surface in the retort andto vaporize such liquid which is free to pass through the tubes A, "B,and from thence through the connection into the heating chamber Fiandthence through the branches '11, i, to the flame orifices orjets J. Thevaporized fuel'is thuszconsumed at the flame orifices or jets J vand asthese jets are below't'he retort and the heating tube :1? a portion ofthe heat is utilized to maintain the retort and'the tube Fin theirproper heated condition.

My burner is simple and durable in construction, efficient inoperation,.and cheap of manufacture. It can be used for :cooking orother domesticpurposes, or it can be used for heating purposesgenerally.

I am aware that changes in the 'form and proportion of parts and in thedetails of 0011- the retort A; and in connection follows: A suitable panstruction can be made without departing from the spirit or sacrificingtheadvantages of my invention, and I therefore reserve the right to makesuch modifications and alterations as fairly fall within the scope of myinvention.

Having thus described my invention, .what I claim as new, and desire tosecure by Letters Patent, is-

1. In a hydrocarbon burner, the retort provided with an internaldiffusing tube, in combination with an elevated tank, a supply pipebetween the tank and retort and which delivers a liquid hydrocarbon uponsaid internal diltusing tube, and a bow-shaped pipe which receives fromthe retort and hasits flame orifices below said retort, for the purposesdescribed, substantially asset forth.

2. In a hydrocarbon burner, theretort having the closed ends and theinternal diffusing tube arranged concent'ricwithi-n the retortand heldin a fixed vposition therein Lby devices which permit of the freepassage of liquid or vapor between the retort-shelltand the difius ingtube, combined with-an elevated ita.n*k, a

supply pipe which-conveys liquid hydrocarbon from said-tank to .theupper side'of the diffusing tube withinthe retort, and a burner-pipehaving its ends arranged to receivefrom the retort and provided withflameorifices below the retort,substantially as described.

3. Ina hydrocarbonburner,-the combination of a retort providedwith'anin'ternal difiu'sin g tube :which'is fixed therein concentricwith-the tube or shell,.a heatingchamber connected by an intermediatepipe with said retort, an elevated tank, a supply ,pipe arranged toconvey liquid hydrocarbon from said tank to'the-u-p- 'per side ofthediffusing tubelin theretort, and a bow-shaped pipe having its endsconnected .to the heating tube and provided with the flameorifices belowthe retort,substantially as and for the purposes described.

In testimony whereof'l affix my signature in presence of two witnesses.
